Equipment for industry：

Rotary Drum Vacuum Filter is applied to process and waste slurries for filtering,

clarifying, cake washing and extraction, and dewatering. Industries served by K-S include inorganic and organic chemicals,

 pharmaceuticals and biotech, plastics, food products, minerals, electric power and other utilities. Specific process

applications are referenced in the Design Section.

Equipment works：

Working principle：The process of the RDVF is continuous. Each revolution of the drum consists of cake formation, cake washing (if needed), dewatering or drying, and cake discharge.

As the drum rotates,it is partially submerged in the feed slurry

Vacuum draws liquid through the filter medium(cloth) on the drum surface which retains the solids

The vacuum pulls air(or gas) through the cake and continues to remove moisture as the drum rotates

The filtrate and air pulled through the medium flow through internal filtrate pipes and pass though the rotary valve and into the filtrate receiver

The liquid stream is separated from the vapor stream in the receiver

Vacuum is applied using a liquid ring vacuum pump or othe means。
